+        memory_corruption_check=0/1 [X86]
+                        Some BIOSes seem to corrupt the first 64k of
+                        memory when doing things like suspend/resume.
+                        Setting this option will scan the memory
+                        looking for corruption.  Enabling this will
+                        both detect corruption and prevent the kernel
+                        from using the memory being corrupted.
+                        However, its intended as a diagnostic tool; if
+                        repeatable BIOS-originated corruption always
+                        affects the same memory, you can use memmap=
+                        to prevent the kernel from using that memory.

+        memory_corruption_check_size=size [X86]
+                        By default it checks for corruption in the low
+                        64k, making this memory unavailable for normal
+                        use.  Use this parameter to scan for
+                        corruption in more or less memory.
+
+        memory_corruption_check_period=seconds [X86]
+                        By default it checks for corruption every 60
+                        seconds.  Use this parameter to check at some
+                        other rate.  0 disables periodic checking.
